I recently upgraded from PK 7.x to PK 8.4.0. I have a macro that calls a vbs script that opens a new email using a template which is determined at the start of the run. I grab a screen of text to the clipboard. Line 33 is the case title but it contains a | character which I was unable to get my macro to ignore. The vbs would not open an email if I had to select which part of the line to use. I decided to parse the line and build my subject out of the first 5 words.

<#> Retrieve case title
<varset>("wordCount=1","") <#> set word number to grab at 1
<varset>("grabWord=_vStrEmpty","") <#> initialize word holder variable
<varset>("gm_caseTitle=_vStrEmpty","") <#> initialize case title
<var_oper>(vFullTitle,"%clipText%",TEXT_GET_LINE,"33","", "0") <#> Get the line from the clipboard data that contains the title
<begloop>(5)
<var_oper>(grabWord,"%vFullTitle%",TEXT_GET_WORD,"%wordCount%",":", "0") <#> grab the next word in the line
<var_oper>(gm_caseTitle,"%gm_caseTitle%",STR_APPEND,"%grabWord% ","", "0") <#> add it to the end of the title string
<var_oper>(wordCount,"%wordCount%+1",CALC_EXPRESSION,"0","", "0") <#> increment the word counter
<endloop>
<var_oper>(gm_caseTitle,"%gm_caseTitle%",STR_APPEND,"...","", "0") <#> add ... to the end of the title string

So, in 7.x, PK was appending the new word onto the end of the string. In 8.4.0, it's appending the full contents of the string plus the new word onto the end of the string. This is freaking out my vbs and it's not creating the email.
